tween intergranular susceptibility in different acid solutions at nearly constant potential. Intergranular corrosion can be prevented by altering the environment as shown in Table III. Removing copper sulfate from normal H2SO4 at 900C (Test 18) prevents intergranular corrosion (Test 16). Also, anodic or cathodic protection

intergranular corrosion test methods . Abstract . Determination of the susceptibility of austenitic stainless steel X5CrNi18-10 to intergranular corrosion (IGC) is performed by measuring the corrosion potential Ecorr in a drop of a test solution with specific chemical composition. It has been shown that a good correlation exists between

to evaluate the intergranular corrosion susceptibility. The corrosion cell used in the DL EPR test comprised Ag.Agcl/KCl(sat'd) as the reference electrode and platinum foil as the counter electrode.

intergranular corrosion had penetrated the .017-inch thick aluminum (AA6061) face sheet. The intergranular attack (IGA) is likely caused by an aggressive crevice environment created from condensed water vapor located between the cold plate and support shelf. To help to assess the current state of other

4. Magnetic susceptibility of minerals . Except for rare monomineralic rocks, rocks consist in general of all three kinds - i.e. diamagnetic, paramagnetic and ferromagnetic - minerals. In order to get an idea of the contribution of individual minerals to the magnetic susceptibility of a rock, Table 1 shows the susceptibility of the most

paramount importance for ultra-high field MRI and fMRI. Assessment of susceptibility artifact correction methods requires knowledge of the susceptibility-induced magnetic field inhomogeneities. While a variety of experimental tech-niques can be used to map the static magnetic field, numer-ical simulations of susceptibility-induced magnetic .

Magnetic susceptibility is the physical quantity describing material properties in the external mag-netic eld [1]. Magnetic susceptibility is de ned as ratio between magnetizationMof the materialin the magnetic eld and the eld intensityH: M ÂmH: (1) All materials can be classi ed by value of magnetic susceptibility into three groups:

the microstructure of this Ni-based superalloy can be designed to fulfill service property requirements. Thus, a great variety of micros-tructures have been explored, together with some slight changes in chemical composition. However, whatever the microstructure may be, this alloy remains sensitive to oxidation assisted intergranular

Intergranular corrosion (IGC) is one of the most common localized corrosion for metals and alloys [1]. Because of the occurrence of IGC, the bonding force among crystal grains can be weakened . There were three test solutions applied. Solution I was a carbonic acid solution: CO 2 gas was purged into 200 ml de-ionized water until the CO 2 .

The intergranular corrosion resistance of the specimens was assessed by the DL-EPR test in accordance with International Standard, ISO 12732-2006 [16]. The specimens were polished with 2000 grit SiC sandpaper, and the test solution was 2M H₂SO₄ 0.01M KSCN 0.5M NaCl at 25 1 .

This study explores the effects of surface machining on the development of intergranular stress corrosion crack nuclei in a sensitised type 304 austenitic stainless steel. The performance of as- machined surfaces in two different states is compared with a nominally stress-free electro- polished surface.

Intergranular corrosion test To examine the intergranular corrosion resistance and sensitization, two electro-chemical tests—the potentiostatic polarization test and the double-loop electrochemical potentiokinetic . Int. J. Electrochem. Sci., Vol. 11, 2016 7129 reactivation (DL-EPR) test—were carried out. .

Intergranular corrosion test ASTM G 28 intergranular corrosion tests were performed on two samples of 70 mm x 10 mm x 3 mm for each heat treatment, with their great axis parallel to the rod length. ASTM G 28 test conditions were strictly applied except'for two points : .
